TRACTION-ENGINE.

SPECIFICATION formingpart of Letters Patent No. 227,259, dated May 4,

Application filed February 5, 1880.

the other end of the said shaft Q is fixed an To all whom it may concern Be it known that I, ALoNzo JILLsoN, of Racine, Racine county, and State of VVisconsin, have invented a newand Improved Traction-Engine, of which the following is a specification.

Figure 1 is a side elevation of as much of the engine as is essential to show the improvement. Fig. 2 is a transverse sectional elevation on line 00 a2, Fig.1. Fig. 3 is a side elevation of the traction-engine, with certain parts removed the better to exhibit other parts, on line y y, Fig.2. Fig. 4 is a transverse sectional elevation on line 2 z of the epicyclic train; and Fig.- 5 is a side elevation of the spur-wheel of the epicyclio train containing the beveled pinions.

Similar letters of reference indicate corresponding parts.

The invention consists in combining sliding journal-boxes, slotted hangers, and adjustingscrews with a cross-shaft and wheels, as hereinafter described.

In the drawings, A represents the engineboiler, supported on the forward or guiding truck, B, and driving-truck O. B is the axle of the forward truck, pivoted centrally to the block 0 under the front end of said boiler A. D D are the front wheels, moving loosely on the axle B. E is the rear axle, firmly and immovably secured to the boiler A at the rear thereof, and having the driving-wheels F F running loosely upon it, while bolted or otherwise secured to the inside of each of these driving-wheels F F are the spur-wheels G G.

J ournaled in suitable boxes H H, on the top of the boiler A, is the driving-shaft I of the engine proper that supplies the motive power, and said shaft I carries on one end the driving-pulley K, and on the other end the pinion L, that passes into the spur-wheel M, which spur-wheel M in turn meshes into the spurwheel N, that, together with the pinion O, is set loosely upon the shaft P, which projects laterally from the side of the boiler A.

Q is a shaft that crosses underneath the boiler A, and is journaled in suitable boxes h h, and carries keyed on one end a spur-wheel, S, which meshes into the pinion G, while on epicyclic train composed of the bevel-wheel T, which is keyed to the shaft Q of the central spur-wheel U, that rides loose on the hub of the bevel-wheel T, and carries in radial open-' ings the beveled pinions V, on stationary radial studs a, or may be keyed to a shaft and the shaft run in bearings fastened to the said spur-wheel U; and the said epicyclic train is further composed of the bevel that run loosely and-spur pinion W, which runs loose on the shaft q and meshes into the pinion or spurwheel G, and drives the truck-wheel F independen tl y of the bevel-wheel T, through which bevel-wheel T motion is transmitted for driving the truck-wheelF. 6 With this arrangement of the spur and bevel wheels and pinions herein shown the traction- .engine can be run backward by a simple reversal of the engine proper that moves the mechanism of the said traction-engine, and 7 when the traction-engine is running forward or backward in a straight line the same rate of motion is imparted through the spur-wheel U and bevel-pinion V to the wheels F F, with which they are connected, and all the said wheels T U V W move as if pinned fast together, the said bevel-pinions V revolving around the shaft Q without revolving on their own axes, while in turning the said tractionengine the unequal rates of motion in the same 8 or opposite directions demanded by the driving-wheels F F will cause the said bevel-pinions V, through the medium of the spur wheels or pinions G G and wheels T W, to rotate upon their own axes, and, with their axes, around 8 theircommon center,(the shaft Q,)without causing any change of motion to the wheel U, so that the same rate of motion may be maintained by the driving-shaft I, and different rates or directions of motion wheels T W, respectively, and there will be no loss of power by the slip of the wheels.

X X represent the slotted hangers secured to the under side of the boiler A and supportbe given to the 0 ing the sliding journal-boxes R R of the shaft 5 Q. These boxes R R are held in place by the bolts or screws 11, that pass up through the slots 0 of the said hangers X X and of the adj ustin g screws, d, that are entered through the ends of the said hangers and bear against the said boxes B R. By means of these screws 1) d the boxes B R can be moved up or down on the hangers X X, and securely held in either position, so that the shaft Q, with its attached wheels or pinions S T, can be moved or allowed to slide down, and thus disconnect the train of gears, in order that the traction-engine may be drawn by horses or motive power other than steam Without unnecessary friction and waste of power, which would result were the gearing not disconnected.

The connection of the gearing maybe renewed by simply turning up the bolt or screws d, so as to crowd the sliding boxes R B again
